Answer:

Step-by-step explanation:

I assume you mean to write a polynomial function. I don't know how righting works.

The simplest one I can think of is

y = 3x⁷

Find a and b if<br>2^a×3^b=12​
krok68 [10]

Answer:

12=12

Step-by-step explanation:

2a = b

a -3b =12

To solve, set one of the equations equal to zero.  The first equation is actually already set to 0.

b = 2a

Now you can plug this equation into the other one, by substituting the b in the equation with this.

a -3b = 12

a – 3(2a) = 12

Now all you have to do is distribute the 3 (multiply the number outside the parenthesis, 3 in this case, by everything inside).

a – 6a = 12

Combine like terms.  Since we have 1 positive a and 6 negative ones, we subtract the two numbers without the signs

6-1 = 5

And take the sign of the larger number.  Since 6 is large and 6 is negative, we are left with

-5a = 12

Now solve for a, which in this case means dividing both sides by -5

a = -12/5

Simplify

a = -2.4

Now that you have a, it’s easy to find b

b = 2a

b = 2(-2.4)

b= -4.8

Now you check your work by plugging your new a and b into either equation to see if it’s true.

-4.8 = 2(-2.4)

-4.8 = -4.8

And just for laughs let’s try the other equation

 

a -3b =12

-2.4 – 3(-4.8) = 12

Distribute the 3 again.  Remember that when two negative numbers are multiplied they become positive.

-2.4 +14.4 = 12

12 = 12

Which value is a solution to the open sentence? 6x – 3 = 27 A. 4 B. 3 C. 5 D. 6
nasty-shy [4]
C.) 5, Using P.E.M.D.A.S you have to multiply first, so replacing the variable X with 5, it should look like this: (6*5) -3=27.  6*5 is 30, 30 subtracted by 3 is 27.
